W. F. ROGERS BROILER OVEN 2 Sheets-Sheet 2 Filed March 24, 1941 IPatented Nov. 18, 1 941 Walter F. Rogers, Oak 'Park, Ill., assignor toCrown Stove Works, a corporation of Illinois 7 Application March 24,1941, SerialNo. 384,376 '3 Claims. (cr me- 340 1 manifoldl-ip. l4designates the top wall of the oven, and I15, the bottom wall. Slidableinwardly and outwardly of the oven is a broiler drawer Hi,

This invention relates to the general art of cooking stoves and ranges,having reference more particularly to improvements in the broiler ovenswhich usually form a part of such stoves and ranges.

More specifically, the present invention relates to broiler ovens of abroadly known type wherein a drawer, rack or the like that supports thebroiler grid or other cooking utensil is slidably mounted. in the ovenand is operatively connected to the oven door, so that, when the door isopened .the drawer or rack is drawn partly out of the oven where thecooking utensil ismore accessible, and, when the door is closed, ismoved to normal position in the oven.

Door-actuated devices of this type for withdrawing and returning thedrawer or rack heretofore employed are more or less complicated andcumbersome; and the object of this invention is to provide a verysimple, inexpensive and efficient broiler oven accessory that willoccupy only otherwise unused space in the oven, will present nointerference with the opening and closing movements of the oven door,and can be easily detached from the door to permit full removal of thebroiler drawer or rack, when necessary for cleaning the same and/or theoven,

A practical and preferred embodiment of the invention is illustrated inthe accompanying drawings, in which- Fig. 1 is a perspective view of agas range embodying my improvement, showing the oven door fully opened,and the broiler drawer and parts carried thereby partly withdrawn fromthe oven.

Fig. 2 is a vertical front to rear section, showing in full lines thedoor closed, and in dot and dash lines a partly open position of thedoor which takes up the lost motion in the drawer withdrawing means.

Fig. 3 is a view similar to Fig, 2, but showing the positions of theparts when the door has been fully opened.

Fig. 4 is a transverse section taken on the line 4-4 of Fig. 2, omittingthe cooking utensils carried by the slidable broiler drawer.

Fig. 5 is an enlarged section taken on the line 55 of Fig. 3.

Fig. 6 is a perspective detail of the link mechanism for moving thedrawer.

Referring to the drawings, Ill designates as an entirety a modern typeof cooking stove or range, in one side of which is a broiler oven,designated as a whole by H, In the upper portion of the oven is a burnerI2 supplied with gas through a the side walls ;of which are equipped,asusual, with spaced ledges I! that support the longitudinal edges of abroiler pan l8, in which latter is seated the removable broiler grid.19., "The drawer I6 is slidably supported on the oven bottom :15through the agency of a pair of rollers 2t and 21 on each side. Theforemost rollers 2i arejournaled .on the inner Sides of a pair ofinwardly facing channel bars '22 that are spotwelded orotherwisesecur'ed on the side portions of the oven bottom I5, and therear rollers 20 are similarly journaled on the lower depending flangesof a pair of Z-bars 23 that are riveted at 24 to the lower cornerportions of the drawer It; the arrangement being such that the rollers20 and 2| on each side are in the same vertical plane.

25 designates the oven door which is hinged at 26 to the bottom memberof the usual frame 21 of the front opening of the oven. A spring 28anchored at its lower end to a fixed member of the stove frame and atits upper end to a curved arm 29, rigid with the door 25, cushions thedown movement of the door and assists its up movement; such a spring invarious forms being a common equipment of oven doors.

Describing now those features wherein the present invention mainly lies,on the inner face of the oven door 25 is a lug 30, towhich is connectedby a pivot pin 3| the outer end of a straight bar link 32. The other endof link 32 is connected by a pivot pin 33 to the upper end of anupstanding shorter link 34 that is itself pivoted at 35 to the outerside of a side wall of the drawer Hi. It will be observed by referenceto Figs. 4 and 5 that the upper pivot pin 33 is long enough to overhangthe top edge of the side wall of drawer iii to which the link 34 ispivoted. Hence, when the door 25 is opened, the pivot pin 33 moves idlythrough a short arc, indicated by dotted lines at X in Fig. 3, above thetop edge of the side wall of the drawer Hi, this idle movement takingplace in a forward direction when the door 25 is moving from th fullline (closed) position to the dot and dash line position shown in Fig.2. When the door 25 is closed, the same idle movement of the pin 33takes place in the opposite direction through the latter part of theclosing movement. From this it will be seen that the link 32 does notmove the drawer H5 in either direction until this lost motion has beentaken up. The reason for this is to prevent any collision of the forwardend of the drawer with the door during the opening movement of thelatter. To prevent any collision of the door with the front end of thedrawer during the first part of the closing movement of the door, Iemploy a pull spring 36 that is anchored at its forward end to a hook 31on the lower side of the bottom wall of the drawer and at its rear endto a hook 38 on the bottom wall l5 of the oven. This spring 36 startsthe drawer I6 back the instant the door 25 begins its closing movement,preventing collision of the door with the front end of the drawer andeffecting the return movement of the latter. As shown in Fig. 4, thisspring 36 is preferably located centrally of the width of the oven anddrawer.

The link 32 is preferably maintained engaged with the pin 3| by a cottorpin 39. When it may b desired to entirely remove the broiler drawer toscour the latter and/or the oven, all that has to be done is to pull outthe cotterpin 39, slip the link 32 off the pin 3|, and pull the spring36 off the hook 31. When the drawer is replaced, the mere reversal ofthese operations reestablishes the operative connection of the door andedrawer, an oven door hinged at its lower edge, a

relatively short swinging link pivoted at one end on said drawer, arelatively long link pivoted at one end to said door above the hingededge of the latter and at its other ,end to the other end of saidswinging link, said links cooperating to form a lost motion connectionof said door to said drawer for withdrawing the latter and a springurging said drawer inwardly of the oven.

2. In a broiler oven device of the class described, the combination of aslidable broiler drawer, an oven door hinged at its lower edge, arelatively short swinging link pivoted at one end to said drawer, arelatively long link pivoted at one end to said door above the hingededge of the latter and at its other end to the other end of saidswinging link, means for limiting the swinging movement of said swinginglink with respect to the drawer in both directions, and a pull springurging said drawer inwardly of the oven.

3. In a broiler oven device of th class described, the combination of aslidable broiler drawer, an oven door hinged at its lower edge, arelatively short swinging link pivoted at its lower end on a side wallof said drawer and of a length such that in all Working positions itextends above the top edge of said side wall, a relatively long linkpivoted at its front end to said door above the hinged edge of thelatter, a pivot pin connecting the rear end of said long link to theupper end of said short link and having a portion overhanging the topedge of said side wall, the overhanging portion of said pivot pin andsaid top edge cooperating to render said long link effective to withdrawsaid drawer when the oven door is opened, and a pull spring detachablyconnected at its forward end to said drawer and at its rear end to theoven bottom and urging said drawer inwardly of the oven.
